How do you know that adapter supports Linux? Where are the instructions 
that show how to use it with Linux?

Can you check the contents of the file /etc/sysconfig/hwconf (any paging 
program like "more" or "less" will work) and see if there's anything in 
there that looks like your ISDN adapter?

Also, I have an Aethra ISDN TA supplied by my ISP (Terra Networks, part of 
Telefónica). It provides control via the standard Hayes AT command set, and 
since it's external and works via the serial port, I control it just like a 
regular modem and NOT like an ISDN modem.

If your ISDN adapter has a serial port, check to see whether you can 
control it with AT commands. If you can, things will be a lot easier. Start 
the program "minicom" and set it to use one of the following: /dev/ttyS0, 
/dev/ttyS1, /dev/ttyS2, or /dev/ttyS3. (Try each until one works.) In each 
case, once you get into the program make sure that local echo is on, and 
then type the command "atz" followed by the Enter key. If you get back an 
"OK" answer, then you can probably use it like an external analog modem 
(except lots faster) and make your life easier.

Please post more detail when you post again, OK?
